Lead-free Perovskite with Distorted [InX] Octahedron Induced by Organic Cation and Enhanced PLQY by Sb Doping.

In-based halide perovskites have attracted a lot of attention because of their unique broadband emission properties. Herein, a series of In-based hybrid perovskites of (HMP)InCl·HO (), (HEP)InCl·HO (), (HMP)InBr·HO (), and (HEP)InBr·HO () were synthesized under the control of halogen ions and organic cations. , , and exhibit obvious photoluminescence properties with peaks at 392, 442, and 652 nm, respectively.

Seeking environmentally friendly halide perovskite photocatalysts: synthesis, structure and photocatalytic performance exploration.

Halide perovskites have high photoelectric conversion efficiency, making them promising candidates for photocatalysis. However, their toxic and unstable nature limits their applications. Here, we successfully synthesised three hybrid Bi-based halide perovskites: (HTMG)BiBr (1), (HEI)BiBr (2) and (HTMA)BiBr (3).
